I'm using HBase 0.20.6.
For column definitions are VERSIONS and TTL mutually exclusive?
For example, what happens if I define a column like so:
create pages, {NAME = 'info', COMPRESSION='gz', VERSIONS=30, TTL =
'2592000'}
Will only one of VERSIONS and TTL be used ? If so, which?

Hi,
I am using Hbase 0.90.4 version and my Hadoop version is 0.20.203. I am
getting the following exception in my HMaster logs when trying to start
HBase:
java.io.IOException: failed on local exception: java.io.EOFException
This is causing my HMaster thread to abort and I am getting
Will HBase 0.92 support MultiHFileoutputFormat and IncrementalLoad for
different Tables?
Is there a comfortable way to make it work for HBase 0.90.4 as well? I
am using Cloudera's CDH3u2.

Which type of installation are you using - distributed or pseudo
distributed?
Can you send us the output of 'jps' from server which should host HMaster,
and as well fractions from log?
Tnx,

You likely have hadoop-core in hbase/lib dir that's wrong, delete it, and copy
one from Hadoop/ dir

Also, Apache Hadoop 0.20.203 isn't a Hadoop version you'd want to use HBase
with in production (lacks 0.20-append branch features). The book link provided
by J-D covers the recommendations.

Just out of curiosity, are there any performance benefits from setting
READONLY to true on tables? I've checked out the HBase book and
Definitive Guide and the API docs, but none of them go beyond a basic
description of READONLY behavior (which seems to be pretty simple :)).

I don't think there is any performance benefit as such. From the
source code, it appears that the only use is to avoid accidentally
updating / mutating a table that you want to keep immutable.
So - setting the read only flag will prevent accidental updates to that table.

No (Look at its API).

Do we know what would need to change in HBase in order to be able to manage
more regions per regionserver?
With 20 regions per server, one would need 300G regions to just utilize 6T of
drive space.
To utilize a regionserver/datanode with 24T drive space the region size would
be an insane 1T.
Region Scalability is definitely an investigation item that has not been
covered yet. We solved the problem with horizontal sharding into multiple
clusters instead of tackling that subject with the timeframe we had. I'm
guessing the 2-level ROOT/META was a response to that problem. On the
